A heel-rand is comthe bedof a suitable press, the block being posed of a strip of leather whichis wedgepreferably composed of cast-iron. In the shaped in cross-sectionand is applied to the block are formed a series of heel-shaped cavisideof a boot or shoe heel opposite the top ties 0, each of which is open atone end.

The follower d is then inserted in the cavity, said follower havingrecesses to receive the studs L. When the several cavities of the blockhave been charged, as indicated, it is placed upon the bed of the pressand the platen of the press is brought down upon the followers (Z, theresult being a compression of the rands, which flattens the wrinklesformed by bending the rands and makes permanent the heel shape impartedto the rands by the walls of the cavities 0'. The pressure beingremoved, the block is removed from the press and the followers areremoved from the cavities. The beds 6 are then lifted from the cavities,thus releasing the completed rands.

As above stated and as shown in Fig. 1, one end of each bed 6 projectssufficiently from the open end of the corresponding cavity 0 to form ahandle. These projecting portions or handles of the beds enable saidbeds to be lifted directly upward from the cavities, so as to remove thecompleted rands conveniently and expeditiously. Said upward movement ofeach bed and a rand carried thereby results in the clearing of the fixedstops 6 hereinafter referred to and which form part of the locking meansto prevent slipping or lateral movement of the parts.

It will be seen that the described appliance is extremely simple andinexpensive in con struction. Any desired number of said appliancesmay-be employed simultaneously in a press, the appliances being piledone upon another-between the bed and platen of the press, so that alarge number of rands may be pressed simultaneously.

It will be observed that the bottom of the block a is flat. This notonly enables the said block to be utilized to form a top plate for aduplicate appliance, but it also insures the resting of the block flatand square upon the platen of a press. The removable members whichoccupy the cavities of the block a have a total thickness exceeding thedepth of the cavities in which they are to be placed, so that the uppersurfaces of the followers (Z can project above the upper surface of theblock a. The upper surfaces of the followers are all fiat, and thereforethey will be equally borne upon by the bottom of the superimposed blockwhen a plurality of the appliances are placed in a press.

We have found that by the use of this appliance we are enabled tomaterially reduce the cost of forming the complete rands ready forapplication to boot or shoe heels as compared with the methods and meansheretofore employed.

The bed A, which is preferably a thin plate of metal, may be providedwith the studs b Z) by suitably cutting the plate to-permit portions ofits material to be turned up, forming the studs 6. The opening thusformed in the plate may be utilized to engage fixed stops 6 driven intothe block a to prevent the endwise movement of the bed 6 out of the moldcavity. To prevent the endwise movement of the follower d out of themold-cavity, the bed 6 may be provided with an ear or stop 6 arranged tobear on the outer end of the follower.

Since the fixed stops 5 project upward from the bottoms of the cavitiesin the block a through openings in the bed-plates b, the said bed-platesare practically locked, so as to be held against lateral movement or amovement that would tend to slip the bed-plates out of the cavities, andthe stud Z) rising from the bed-plates and entering recesses in thefollowers cZ prevents any slipping movement of the followers out oftheir proper positions in the cavities and on the bed-plates. hen thebeds are provided with ears or stops 6 said stops furnish additionallocking means to prevent any slipping movement of the followers.

While we have stated that the block a and followers (Z may be made ofmetal, we do not limit ourselves to this material. The block andfollowers may be in many cases made of wood.

We claim- 1. A rand-pressing appliance comprising a block having aheel-shaped cavity, a 'heelshaped follower adapted to enter the cavity,

and a removable bed fitting between the fol-- lower and bottom of thecavity, said bed being longer than the cavity so as to project therefromand form a handle whereby ashaped rand may be lifted from the cavity.

2. A rand-pressing appliance comprising a block having a heel-shapedcavity, a heelshaped follower adapted to enter the cavity, and aremovable bed fitting between the follower and bottom of the cavity,said plate being longer than the cavity so as to project therefrom andform a handle whereby'a shaped rand may be lifted from the cavity, thecombined thickness of the follower and bed exceeding the depth of thecavity whereby the appliance is adapted to be subjected to the action ofa press.

3. A rand-pressing appliance comprisinga I block having a heel-shapedcavity open at one end, a loose heel-shaped bed insertible in the cavityand adapted to project from the open end thereof, and a heel-shapedfollower adapted to enter the cavity, said block and bed having lockingmembers to prevent endwise movement of the bed, the bed having also alocking member to prevent endwise movement of the follower.

In testimony whereof we have aflixed our signatures in presence of twowitnesses.
